It is a stabilized pressure water supply device&comma; widely used in air-conditioner&comma; heating equipment&comma; water distribution systems and so on&period; It can replace traditional expansion water tank&comma; reduce the pump start times&comma; and absorb part of system water swelling capacity&comma; be easy to supply water automatically&comma; exhaust automatically&comma; decompression automatically and automatical overvoltage protection and so on&period;

operational principle Constant pressure water supply device works depending on the system swelling characters&period; Its component parts mainly are capsule type constant pressure tank&comma; pump&comma; pressure switch&comma; control cabinet&comma; safety valve&comma; underframe&comma; connecting line and so on&period; When the system temperature and the water volume increase&comma; the system pressure increases&comma; and at this time some part of water enter into the capsule of capsule type constant pressure tank&comma; then the capsule swells and compress the tank gas until the system pressure and tank pressure is balance&period; The gas expansion in tank presses the capsule water into system when the system water volumn is reduce&comma;and system pressure falls&period; If the supplied water still can not meet the requirement of the water quantity needed by system&comma; the pump start and supply water&period; The electro connecting pressure gauge and control cabinet control the pump opening and closing&period; The electric connect has two setting pressure spot&comma; one is pump starting pressure P1&comma; and another is closing pressure P2&comma; P1&comma;P2 is the lowest setting pressure spot and the maximum working pressure respectively&period; The control cabinet control the pump start and supply water to system after supplying water through capsule type constant pressure tank but the system pressure still can not reach P1&comma; and the pump stop when it supplies water until the system pressure and tank pressure is greater than the P2&period;

Constant pressureAir pressure tank precharge pressure 2~3 bar&comma; constant pressure pump and pressure relief valve control the pressure and keep the change range in ±0&period;2bar&period; The swelling water flow in and flow out from constant pressure through two separated expansion pipeline&period;

Exhausting gasDuring the exhausting process&comma; high pressure circulating water enters into atmospheric tanks and after decompression &comma;gas and water separated&comma; then the precipitated gas enter into atmosphere through exhaust valve&period;

Supply waterThe water which is lost because of exhausting gas and pipeline leakage can be monitored constantly by control unit&comma; and once it is lower than the setting value&comma; it will supply water automatically&period; The water quantity in diaphragm tank is determined by water level sensor&period;

DrainageThe system water enter into basic tank because its temperature increasing result in pressure is very high&comma; and when the basic tank water quantity exceed the preset value&comma; it automatically drainage too much water in order to guarantee the tank will not undertake pressure&period;

Performance characteristicsGas charging for one time can be used for long time&comma; and user do not need to prepare for gas charging device&period;It is convenient to relocate and hide in order to reconstruct and enlarge project&period;Building speed is fast &comma; construction and installation is easy&comma; building time is short&comma;and the construction cost is low&period;It can replace elevated tank and water tower&comma; and it is benefit to structure earthquake-resistant &period;Reliable operation&comma; maintenance is simple&comma;and it is easy to management&period;It can weaken the water flowing noisy&comma; the pipe resist force and the effective of water hammer&period;For the electric control cabinet &comma;modern design &comma;complete function&comma; automatical control and also can be operated by hand&period; The fire fighting device can be added the function that the pump make routing inspection automatically and regular to prevent from rusting&period;Water flows in closed system&comma; and it is not easy to be contaminated&period;During engineering construction&comma; it can be used in construction first&comma; then used in engineering so that save temporory structure cost&period;Application areaIndustrial water supply&comma; urban housing area&comma; multi-storey and high-rise buildings&comma; water supply and irrigation in countryside&comma; military installations&comma; railway&comma; dock&comma; construction site&comma; building in earthquake area&comma; fire fighting water supply &comma;boiler room&comma; thermal substation and every kinds of low temperature hot water heating system&period; It also can transport clean water which temperature is lower than 80 °C and other liquid which physical and medical characteristic is same as clean water&period;

Operation notice for control cabinet of submersible sewage pumpThe control cabinet has two starting method&colon;manual operation and automatic operation&semi;Return three position knob to manual position when the manual operation start&comma; then press the related button to start or close&period;The pump running indicator light when the pump works&period;When it automatically works&comma; the float switch and pressure testing equipment needs to be connected to control cabinet according to the connecting terminal &comma;then return the three position knob to automatic position&period; The open and start for automatic working accords to the float switch and the signal of pressure testing equipment&semi; when the pool level is satisfy the condition&comma; the system pressure is low&comma; then the pump is started and added pressure&semi; when the system pressure is high&comma; the pump is closed&semi; when the system works automatically&comma; and the two pump are all in good condition&comma; different pumps will be started by turns&semi; when one pump is brokendown&comma; another one will work automatically&comma; and when pump overloads&comma; the fault indicating lamp will light&period;
